Abstract: The invention relates to improvements in the field of injection molding technology. Among other things, a method for injection molding plastics parts (2) is proposed as an improvement, in which, to produce a plastics part (2), liquefied plastics material is injected into a mold cavity (4) of an injection molding tool (3) equipped with a core (5). The method is characterized in that the core (5) is inductively heated before the plastics material is injected.

Abstract: In a fastening arrangement for the positionally correct fastening of a device to a structural part of a motor vehicle, the at least one screw means is arranged on a tolerance-compensating part, wherein the tolerance-compensating part is fixed to the structural part by means of a joining material which is selected from an adhesive or a plastic liquefied by ultrasonic welding, and wherein the tolerance-compensating part is adjusted in position relative to the structural part. A method for the positionally correct fastening of a device to the structural part of a motor vehicle makes use of a tolerance-compensating part which is joined to the structural part by making use of a joining process in which a joining material is used, the joining process being selected from the group consisting of: adhesive bonding with an adhesive as the joining material, ultrasonic welding with a plastic as the joining material.
